    摘要: A geared drive assembly (10) comprising the driven gear (12) arranged to mesh with the driving gear (14) and a rotary actuator operatively connected to the driving gear (14) by the pulley belt (22) engaging with an first pulley wheel (18) of the rotary actuator and a second pulley wheel (24) rigidly and coaxially connected to the driving gear (14), wherein the pulley belt (22) comprises first (26) and second (28) pulley belt portions extending between the first (18) and second (24) pulley wheels, wherein the first pulley belt portion (26) is maintained, in use, under tension, and wherein the second pulley belt portion (28) is slack, in use. Advantages of the invention, compared with known anti-backlash gearboxes, include: significant weight reductions, reduced complexity, reduced drag, smaller motor sizes, reduced part count, reduced play and backlash. Embodiments of the invention may advantageously provide a lightweight, simple anti-backlash gearing assembly that are particularly suited for use in motorized camera mounts, e.g. pan/tilt heads.

    摘要: An optical navigation system comprising a camera oriented to face towards a plurality of markers located at spaced apart locations from the camera, calculating means adapted to calculate an angle subtended between pairs of markers, the subtended angles being calculated by monitoring the pixel locations of the markers in a series of images captured by the camera, the optical navigation system additionally comprising means for creating a three-dimensional model whereby the location of the camera relative to the markers is determined by triangulating the subtended angles in the three-dimensional model.
